Extracted text: Cholesterol levels of adult males are approximately normally distributed with a mean of 224 mg/dL and a listed variance of 475.24. Some researchers claim that the variance of cholesterol levels of adult males is less than 475.24. Suppose that we want to carry out a hypothesis test to see if the actual variance of cholesterol levels of adult males is less than 475.24. State the null hypothesis He and the alternative hypothesis H, that we would use for this test. H :1 , :0 H O口 ロRロ D=D0 ロチロ
